Field Application of IPCS Technique in Block Wei 95 of Mazhai Oilfield

A specific project is designed for IPCS (indepth profile control and surfactant flooding)testing according to the geologic and development situations of block Wei 95 in Mazhai oilfield A field testing is conducted The result shows that the mass production of tested well group increases from 196 2 m 3/d to 206 0 m 3/d, oil production increases from 18 5 t/d to 24 9 t/d, and producing fluid level goes up to 1 320 m from 1 351 m, water cut reduces from 91% to 88%, from which the purposes to stabilize the oil prodution and control water are achieved
